摘要

The synergistic effects of plant growth-promoting rhizobacteria and an arbuscular mycorrhizal fungus (Glomus fasciculatum) on plant growth, yield, and nutrient uptake of wheat plants were determined under field conditions. The triple inoculation of Azotobacter chroococcum with Bacillus and Glomus fasciculatum significantly increased dry matter by 2.6-fold above the control. Grain yield of plants inoculated with A. chroococcum together with Bacillus sp. and G. fasciculatum was 2-fold higher than that of non-inoculated plants, at 135 days after sowing (DAS). The maximum increase in grain protein (255.2 mg/g) was observed in plants inoculated with A. chroococcum with Bacillus sp., G. fasciculatum, and Penicillium variabile, while the minimum grain protein (113.7 mg/g) was with a single inoculation of G. fasciculatum. The higher N content (33.6 mg plant-1) and P content (67.8 mg plant-1) in wheat plants were observed with the co-inoculation of A. chroococcum with Bacillus sp. and G. fasciculatum. The N and P contents of the soil at 135 days after sowing differed among treatments. Addition of P. variabile to single or double inoculation treatments negatively affected the measured parameters. Populations of A. chroococcum, phosphate solubilizing microorganisms, percentage of root infection, and spore density of the arbuscular mycorrhizal fungus in some treatments increased at 80 days after sowin. The findings show that the multiple inoculations with plant growth promoting rhizobacteria consistently increased the growth and yield, N and P concentrations, and quality of wheat grains.
